Description

A kind of soluble chemical wax ball clearing and preparation method thereof and application method
Technical field
The invention belongs to technical field of petroleum extraction, it is related to a kind of soluble chemical wax ball clearing and preparation method thereof and uses Method.
Background technology
Crude oil is a kind of typical waxy crude oil, and wax deposition is serious, this is easy for causing oil well wax card, disconnected bar, or even is formed " well of lying ".Cost for oil production is caused to rise, subsequent processing problem increases.In conclusion paraffin deposit is asked during oil recovery sum aggregate is defeated Topic seriously affects always the links of Petroleum Production and processing, in oil-gas reservoir reservoir, winning apparatus, gathering line and processing Can all occur paraffin deposit phenomenon in equipment.In recent years, as the exploration of oil and natural gas, exploitation and PETROLEUM PROCESSING are to depth The rapid development in direction studies and solves the problems, such as that the urgency of paraffin deposit and importance are further prominent.Waxy crude oil is efficiently adopted Go out and the theory and technology of safety, economic conveying be always crude oil in China exploitation, the development of Oil & Gas Storage field one of direction, It is also got growing concern in international academic community and engineering technological.
Field application most wide, most popular still paraffin removing with chemical method method and physics wax removal, wherein Changqing oilfields use at present The method of physics wax removal, principle are exactly to be collided in the duct with the deposition wax of inner wall of the pipe using ball, it is made to fall off, from And achieve the effect that wax removal.But carried of crude oil pipeline there may be deformation during carried of crude oil, lead to ball not It can pass through, so as to cause carried of crude oil line clogging.
The use of solvent type paraffin remover in recent years is common method:Water base paraffin remover, oil-base paraffin remover, emulsion-type wax removal Agent.But solvent type paraffin remover has using disadvantage, solvent toxicity is big in oil-base paraffin remover, inflammable, explosive, easily diluted by crude oil, Thus it is restricted its application.For water base paraffin remover based on surfactant, but since surfactant price is high, use is dense Degree is big, is easily diluted by crude oil, and wax removal efficiency is low.Emulsion-type paraffin remover remains the wax removal effect of organic solvent and surfactant Fruit, but fail to overcome and the higher disadvantage of larger organic solvent usage amount is poisoned to human body.
Invention content
For problems of the prior art, the present invention provide a kind of soluble chemical wax ball clearing and preparation method thereof and Application method, paraffin removing with chemical method ball have the double action of physics wax removal and paraffin control with inhibitor, can solve wax in carried of crude oil pipeline Deposition problems.
The present invention is to be achieved through the following technical solutions:
A kind of soluble chemical wax ball clearing, is solid forms, in parts by weight, including following raw material:It lives on surface 60-104 parts of agent of property, 7-27 parts of thickener.
Preferably, surfactant is odium stearate, hexadecyltrimethylammonium chloride, cetyl trimethyl bromination One or more of ammonium, sodium laurate, octadecyltrimethylammonium chloride, Cetyltrimethylammonium bromide.
Preferably, surfactant includes:45-80 parts of odium stearate, 8-12 parts of hexadecyltrimethylammonium chloride, 16 7-12 parts of alkyl trimethyl ammonium bromide.
Preferably, thickener includes:2-10 parts of sodium carboxymethylcellulose, 2-10 parts of polyacrylamide, sodium polyphosphate 2-7 Part.
Preferably, further include 1-10 parts of n-docosane.
Preferably, further include 3-8 parts of ethylenediamine tetra-acetic acid.
A kind of preparation method of the soluble chemical wax ball clearing, raw material is proportionally added in absolute ethyl alcohol, stirring Uniformly, it adopts and is molded with a mold, it is dry, obtain soluble chemical wax ball clearing.
Preferably, drying temperature is 80-100 DEG C, drying time 36-48h.
A kind of application method of the soluble chemical wax ball clearing, length are less than the petroleum pipeline of 5km, monthly add wax removal Ball 2~4 times, adds 2~3 pieces every time;
Length monthly adds wax ball clearing 3~5 times in the petroleum pipeline of 5km~10km, adds 3~4 pieces every time;
Length is more than the petroleum pipeline of 10km, monthly adds wax ball clearing 3~5 times, adds 3~6 pieces every time;
Wherein, when adding wax ball clearing, the time interval that adjacent two pieces of wax ball clearings add is not less than 1~30min.
Preferably, the diameter of the wax ball clearing added is smaller 10~20mm than the internal diameter of petroleum pipeline.
Compared with prior art, the present invention has technique effect beneficial below:
Using surfactant and thickener as raw material the soak cleaning ball of solid forms is made, on the one hand, solid in the present invention The wax ball clearing of form has certain mechanical strength, the pressure of 0.3MPa~0.5MPa can be born, to play physics wax removal Effect;On the other hand, there is the surfactant in wax ball clearing certain solubility, surfactant to be dissolved in crude oil In crude oil, lipophilic group is attached to wax surface, and hydrophilic group is contacted with crude oil, to form one layer of hydrophilic film on the surface of wax, prevents The only deposition again of wax, to achieve the effect that wax control.Thickener therein can prevent surfactant in aqueous crude oil In quickly dissolve, and lose physics wax removal effect.The wax ball clearing of the present invention lives surface unlike existing paraffin removing with chemical method agent Property agent dissolving the paraffin remover of solution state is made in organic solvent, therefore poisonous and hazardous organic solvent, ring need not be used Border is friendly, avoids polluting.The wax ball clearing of the present invention has the function of physics wax removal and paraffin control with inhibitor simultaneously, can preferably save into This.
Further, n-docosane is added, the dissolubility of wax ball clearing can be increased, enable wax ball clearing at the appropriate speed Dissolving, the surfactant of dissolving enter in crude oil, play the role of paraffin control with inhibitor.
Further, ethylenediamine tetra-acetic acid is chelating agent, and surfactant is enable adequately to be contacted with wax, and and second Ethylenediamine tetraacetic acid (EDTA) forms stable chelate.
The present invention, by dissolution of raw material, is then adopted to be molded with a mold wax ball clearing is made using absolute ethyl alcohol, and method is simple, operation It is easy, and toxic solvent need not be used, it is safe and non-toxic.Obtained wax ball clearing can play the role of physics wax removal and rise To the effect of paraffin control with inhibitor.
The wax ball clearing addition method of the present invention, adding quantity can be adjusted according to on-site actual situations, according to pipeline Length adjustment adds quantity, can also be adjusted according to line clogging situation, if line clogging is more serious, increases its throwing Addend amount and add number;The straight of wax ball clearing can also be adjusted according to the pipeline of different-diameter, the different pipeline of wax deposition situation The diameter of diameter, general wax ball clearing is smaller 10-20mm than pipeline internal diameter, for the serious pipeline of wax deposition, first adds the wax removal of minor diameter Ball adds the wax ball clearing of major diameter, to reach best wax removal effect after so that it is removed a part of wax deposition of tube wall.
